Patent GB-842653-A (GB)
Title: Ultrasonic inspection apparatus
IPC: G01N29/40
Filed: 1957-05-01
Abstract: 842,653. Ultrasonic inspection devices. OBRAZ, J. May 1, 1957 [May 10, 1956], No. 13889/57. Class 40(7). Relates to ultrasonic pulse-echo inspection and measuring apparatus wherein a pulse is produced of duration proportional to the thickness of a workpiece or the depth of a flaw. According to the invention a gated amplifier 4 receives both the transmitter 1 pulse and the echo signals from workpiece 3, the amplifier being normally biased to low sensitivity but being capable of passing the transmitter pulse to the input of multivibrator 5 to trigger it from a first to a second stable condition to produce a gating pulse fed back to the amplifier to increase its sensitivity so that the first echo signal is passed to the multivibrator to terminate the gating pulse. The multivibrator output is integrated by unit 7 which feeds moving-coil meter 8 calibrated in distance. The thickness of the workpiece or the depth of a flaw therein is thus measured without interference from the effects of later echoes. To prevent amplifier blocking by the leading edge of the gating pulse an integrator may be inserted between the multivibrator output and the amplifier input.

Abstract: 1502830 Pipe-line pigs T D WILLIAMSON Inc 17 June 1975 [19 July 1974] 14001/76 Divided out of 1502829 Headings G1N and G1S A pipe-line being laid on the sea bed from over the stern of a floating barge (10) Fig. 2 (not shown) contains a pipe-line pig 15, Fig. 1, connected electrically and mechanically by a cable 16 to a pipe line up clamp 17 controlled by a rod 18, a console 22 containing read-out means to indicate any kinks or dents in the pipe detected by the pig. The pig comprises a central body 23, Fig. 3, having a tubular portion 23a, Fig. 5, and plates 23b 23c fixed thereto. Brackets 23d and 23e carry bellcrank levers 25 mounting pipe engaging rollers driven by reversible motors 45 and clutches and constructed as shown or as in Fig. 10, the rollers being biased outwardly and arranged so that the two sets over the whole of the internal surface of the pipe. Plates 27, 28 connected to the roller mountings and slide on an assembly of rods 29, 30 joined by an intermediate plate 31, the slide assembly being supported on the pig body by plates 23b, 23c abutted by springs 32, 33 urging the rollers outwardly. In operation when one or more rollers encounters a dent it moves inwardly causing one of the plates 27 or 28 to slide on the slide assembly and move a push-rod 37, Fig. 5, to operate a potentiometer 39 via a last motion connection 40. The potentiometer 39 so connected to a constant current source 54, Fig. 6, via a calibrating potentiometer 55 and produces a voltage which is proportional to pipe diameter that is applied to digital voltmeters 56, 60, the reading on 56 being locked in and gated to the comparators 63, 64 and the printer 58. If the voltage is outside the limits set by maximum or minimum switches 67 a respective one of alarms 65, 66 is sounded. The A.C. power oscillator 68  is then momentarily switched on to release solenoid 43 which returns the slider of potentiometer 39. The output of digital voltmeter 60 is then gated to the size compartor circuit and the printer just as was voltmeter 56 to provide evidence that 39 has been reset. The time of day from clock 59 and an events count from counter 62 are also printed. Means are also provided to connect the memory means in the pig to the read-out means 58 for giving a periodic reading of the output stored in the memory whilst the pig as in the pipe, and after one output read-out another output may be released to the memory means by a release solenoid 43 in the pit. The pig in Fig. 7 (not shown) is modified as that when one or more rollers encounter a dent the entire slide assembly moves to move all of the rollers inwardly so that should the pig become stuck in the pipe a second following pig could be made to push on a bumper plate 74 and collapse all the rollers to enable the first pig to be dislodged.

The first corrugated slab, however, may be subsequently rolled flat and thinned to sheet form without slitting. Figs. 3 and 4 show alternative pass forms for the rolls A, Fig. 4 pass being used when angle bars are subsequently required. The rolls A are covered with a mild steel, nickel chrome or other protecting metal 11 to prevent damage by the molten metal. The flanges 12 for retaining the molten metal are also of heat resisting metal. Rollers J, Fig. 2, take any end thrust on the rolls A. 9 is a water cooling chamber in the rolls A.

Title: Improvements in or relating to the preparation of glycols from oxides of olefines
IPC: C07C29/10
Filed: 1936-05-19
Abstract: Glycols are made by reacting the olefine oxides with water in presence of oxalic acid.  The temperature may be 50--100 DEG  C. and the quantity of the oxalic acid may be 0,1--0,5 per cent. After the reaction the oxalic acid may be precipitated by milk of lime.  In an example, equivalent quantities of water and ethylene oxide are introduced into a 20 per cent glycol solution containing 0,1 per cent of oxalic acid at 75 DEG  C.  After precipitating the oxalic acid glycol is separated by distillation.  About 10 per cent of the product is diethylene glycol, but the relative quantities of the two products may be varied by varying the quantity of water present in the known manner.  Propylene glycol may be prepared similarly.
